About the Product

Packed with the latest research and developments, NUTRITION & DIET THERAPY, 12E introduces the essentials of nutrition concepts, good health, and client care -- equipping LPN/LVN nursing students with a solid foundation in nutrition. The text enables students to more effectively help clients improve their nutrition and overall health, especially as our nation faces higher rates of preventable chronic disease as a result of poor diet quality and physical inactivity. Extremely user friendly, the text is organized around three simple concepts: Section 1 covers the fundamentals of nutrition, Section 2 explains nutrition over the life cycle, and Section 3 addresses medical nutrition therapy. New information is included on "Healthy People 2020", DIETARY GUIDELINES FOR AMERICANS 2015-2020, obesity prevention and treatment, lifestyle medicine, diabetes, celiac disease, irritable and short bowel syndrome, and more. In addition, MindTap and numerous hands-on activities maximize student learning.
